Surgical treatment of multiple impacted supernumerary teeth in a cleidocranial dysplasia patient

To report a case of cleidocranial dysplasia (CCD) with 15 supernumerary teeth and review the relevant literature. Diagnose and treat a CCD patient with 15 impacted supernumerary teeth in the maxilla and mandible. When CCD is accompanied by supernumerary teeth ambushed in the jaw and does not affect the health of the body, it can be regarded as a part of normal bone tissue. If X-ray or computed tomography examination shows that supernumerary teeth affect permanent tooth eruption, the replacement process of adjacent teeth and permanent tooth eruption should be closely observed, and supernumerary teeth should be extracted in time if necessary.
